Mentha oil futures prices fell by 0.30 per cent on Thursday as traders indulged in profit-booking at higher prices amid fall in demand in the spot market.
Increased arrivals from producing belts in Uttar Pradesh also put pressure on the prices.
At the MCX counter, mentha oil for November contract declined by 0.30 per cent to Rs 533.60 per kg clocking business volume in 201 lots.
Similarly, mentha oil for delivery in December contract eased by 0.26 per cent to Rs 540.20 per kg, in business turnover in 53 lots.
Fall in mentha oil prices was mostly due to profit-taking by speculators and subdued trend in spot markets, traders said.
